What websites or tools are you using to test the speed of your server? This may be a generic question or asking the question incorrectly, so what variables do you look for when testing a server's speed and what is acceptable?
I currently have a shared hosting plan but I am considering upgrading to a business shared plan. I don't want to go dedicated yet because my blog doesn't get much traffic. However, it is important the pages load fast. I do as much on-page optimization as possible.
